项目摘要

This research has been done to develop a Mist Singlet Oxygen Generator (Mist-SOG) for Chemical Oxygen Iodine Laser. In the Mist-SOG, the reaction between Basic Hydrogen Peroxide (BHP) and Cl_2 gas occurs on the gas-liquid interface. The reaction surface of the BHP is increased by making small diameter droplets of tens micron. The goal of the Mist-SOG is a complete usage of HO_2 ion through a single pass operation. The obtained results are summarized as follows;1. BHP is made from 45wt% H_2O_2 and 48wt% KOH in our experiment. Therefore the limit of BHP utilization is 42%. In the experiment, 79% Cl2 utilization, 80% yield and 41% BHP utilization were obtained at the BHP flow rate of 2.2ml/s and Cl2 flow rate of 9.0mmol/s for the 15μm BHP droplets.2. Mist-SOG generates much more water vapor than conventional SOG because the heat capacity of the BHP is small. The water vapor vapor deactivates the excited iodine. In order to remove the water vapor, we developed a jet-cold trap. Water vapor partial pressure reduced from 3.4 Torr to 1.1 Torr at the BHP flow rate of 2.2ml/s and Cl2 flow rate of 3.5 mmol/s for the 65μm BHP droplets.3. A numerical simulation code for Mist-SOG is developed. The heterogeneous quenching probability of O_2(1Δ) for the surface of BHP was determined by a comparison between the experimental and calculated results, and was found to be 2x10^<-3>. For 15μm droplets diameter, 50% BHP could be utilized with an output of 64% O_2(^1Δ) yield and 88% C_l2 utilization.

本研究旨在研制一种用于氧碘化学激光器的雾状单重态氧发生器（Mist-SOG）。在Mist-SOG中，碱性过氧化氢（BHP）与Cl_2气体的反应发生在气液界面。通过制造数十微米的小直径液滴来增加BHP的反应表面。Mist-SOG的目标是通过单程操作完全利用HO_2离子。所得结果总结如下：1.本实验采用45wt%H_2O_2和48wt%KOH为原料制备BHP。因此，BHP利用率的极限为42%。在BHP流量为2.2ml/s，Cl 2流量为9.0mmol/s时，15μm BHP液滴的Cl 2利用率为79%，产率为80%，BHP利用率为41%.由于BHP的热容量小，Mist-SOG比常规SOG产生更多的水蒸气。水蒸气使激发态碘失活。为了去除水蒸气，我们开发了一种喷射冷阱。对于65μm的BHP液滴，在BHP流速为2.2ml/s和Cl 2流速为3.5mmol/s时，水蒸气分压从3.4Torr降低到1.1Torr.开发了Mist-SOG的数值模拟程序。通过实验与计算结果的比较，确定了O_2对BHP表面的非均匀猝灭几率（1Δ）为2 × 10 ~（-1）<-3>。当液滴直径为15μm时，BHP的利用率为50%，O_2（^1Δ）的产率为64%，Cl_2的利用率为88%。
